用途及特點
本機床是在本廠生產的JK3M8320型數控梯形活塞環端面磨床的基礎上,充分考慮了國內活塞環制造廠的生產情況和承受能力,并結合吸取了國外最新設備優點和相關加工技術,改型設計,開發研制出來的。彌補了過去磨床布局不合理、剛性不高,導軌不耐磨、磨頭軸承易磨損、下料操作不方便等不足。電氣柜裝有空調,確保系統正常運行。本機床夾具體可直接用自身砂輪圓周修整,為工件的磨削精度提供了可靠的保證。滾珠絲桿和導軌副全部裝有潤滑點，自動潤滑系統提供可調節流量和間隔的潤滑。

SKTM Keystone RingCNC GrindingMachine
Theapplication and feature ofthe machine
This machine is innovatively designed and developed based on JK3M8320 keystonemachine and advantages on latest foreign machines. The production capacity and affordabilityof piston rings manufactures have been considered to a basis ofoptimal design.The machine has advantages of reasonable layout, high rigidity, anti-abrasive of guide wayand spindle bearings. Electric cabinet is equipped with the air conditioner which keeps themachine running stable and reliable. The toolingon the machine can be grinded by itself, so ringscan achieve high grindingaccuracy.
The sliding table’s guide and ball screw have applicable lubrication points. Automaticlubrication unit is equipped and interval and flow of lubrication be adjusted. All ofthese designsarenecessaryin orderto achieve the best performance.
